Abstract An irrigation water screen comprising an upstanding cylindrical housing having an entranceway adapted to be connected to an irrigation water supply pipeline and a multiplicity of exitways in the housing, each exitway being adapted to receive a secondary water pipeline, a concentrically disposed cylindrical screen in the housing adapted to cover each of the exitways and having an inverted V-shaped bottom portion adjacent the entranceway in the housing, and a releasable flushing cap carried by the housing in the terminal end of the housing opposite the entranceway, one of the terminal ends of the caps being engageable with the cylindrical screen in the housing. The flushing cap is provided with a bulbouslike bell-shaped body adapted to be retained in the housing by a retaining spring ring urging against the uppermost shoulder of the cap formed by the body and a return position provided in the housing at the terminal end opposite the entranceway thereof. The flushing cap may be removed and replaced in the housing by pivoting the cap and articulating the lower recede portion of the cap body about the retaining spring ring in the housing to provide means by which the screen may be removed for cleaning. The flushing cap is provided with a wall in the end opposite the terminal end adjacent the screen in the housing when the cap is in place in the housing, the wall being provided with an exitway adapted to be connected to a commonly known water valve and being operable to flush the irrigation water screen of this invention while the irrigation water system to which it is attached is in operation.
An irrigation water screen comprising an upstanding cylindrical housing having an entranceway at one of its terminal ends adapted to be threadably connected to an irrigation water supply line, the opposite terminal end of said housing issuing inwardly with respect to the center of the housing to form a shoulder portion, and an annular ring suitably fastened to the inNer wall of said housing and spaced below the shoulder portion of the housing; a spring-loaded sealing ring means disposed between said shoulder portion and said annular ring; a bellshaped flushing cap issuing inwardly at one of its terminal ends to form a bulbouslike body portion having an exitway in a wall opposite said terminal end adapted to be threadably connected to a water valve, the said flushing cap being normally disposed in the housing and retained therein by the said spring-loaded sealing ring means urging inwardly against the upper shoulder portion formed by the bulbouslike body portion of the bell-shaped cap, said cap being removable therefrom by pivoting said cap to the lower recede portion of the bell-shaped cap and articulating the cap about the said sealing ring means; a multiplicity of laterally extending exitways disposed in the housing below the terminal end of said flushing cap operable to receive irrigation water pipelines, an upstanding cylindrical filter screen concentrically disposed in the housing having a V-shaped bottom bar portion adjacent the entranceway of said housing, said cylindrical screen extending from the terminal end of said housing adjacent said entranceway upwardly to the terminal end of said flushing cap and engageable therewith when said cap is in its normal place in said housing so that the screen covers said opposing exitways in said housing.
